You create a moving 5-foot-radius, 10-foot-high barrier lasting 5 minutes, preventing a specific creature type from entering or affecting the area. The effect ends if you move to include one into the cylinder.
An ethereal barrier surrounds the target, shielding against the malevolent presence and dark energies of the undead. Within this protected space, the individual gains resilience against the undead's corruptive touch and unholy influences.
